METAL END STRUCTURE FOR RAILWAY-CARS.

Specification of Letters Patent. Patented Aug, 30 1921 Application filedKovember 29, 1919. Serial No. 341,455.

T 0 aZZ w ham it may concern useful Improvements in Metal End Structuresfor Railway-Cars, of which the followin is specification.

My invention relates to a sheet metal end other as will provide thegreatest strength and rigidity at the point where such strength andrigidity will be most effective in resisting the shocks and strains dueto the inertia thrusts of the cargo and which will also rcinforce theend of the car so that it will withstand the various other stressesresulting from the weaving movement the car or other-causes; V

Another object of the invention is to provide a sheet metal endstructure, of the above character, in which the cross sectional of thereinforcing ribs may be greatest at the point where strength is mostdesired .without conflicting with the provisions oi the InterstateCommerce" Commission relating to clearances between adjacent cars.

The invention has for further objects the novel arrangement,construction and combination of parts hereinafter described and claimedfor carrying out the above stated objects and such other objects as willappear from the-following description.

The invention is illustrated in certain preferred embodiments in theaccompanying drawings wherei;

end construction applied Fig. 11, is a vertical sectional View takenthrough the center of the structure shown in Fig. 8, and 1 Fig. 12 is avertical sectiona'lview illustrating a further modification.

Like characters of reference designate like parts.

Referring first to Figs. 1 to 8 inclusive of the dra vings; 10designates the corner posts one end of a car; 11 the end sill; 12 theend plate; 13 the ridge pole; 14 the outer side sheathing; 15 the innerlining; 16 the roof boards and 17 the flooring of the car. I

. The end wall of the structure shown in the above figures comprises apanel composed of metal sheets 18 and 19 which are overlapped andsecured together along vertical lines by rivets 20: The outer verticaledges of these sheets are formed with flanges 21-422, respectively,which overlap the side sheathing 1 1 of the car and are secured to theside framing by bolts 23 which extend through the corner posts 10. Thelower edges of the sheets 18-19 are formed with flanges 24 which extendunder the flooring 17 so as to provide a grain proof connection at thispoint and are secured to the under framing of the car by bolts 25 andthe. upper edges of the sheet are secured tothe end plate 12 by bolts26. These sheets are formed with a plurality of parallel Verticallyextending corrugations 27 which merge one with another and extendsubstantially from the flooring of the car to the roof thereof. Thecorrugations 27 are preferably pressed inwardly from the plane of thesheets so as to provide maximum clearance between adjacent cars andterminate with the usual tapered terminals within the upper and loweredges of the sheets. A vertically disposed sheet 28 is secured,preterably, to the outer face of the sheets 18-49 adjacent the verticalcenter of the end wall so as to overlap the adjacent edges of thesesheets. The sheet 28 is provided with a plurality of outwardly pressedcorrugations 29 which are oppositely disposed with relation to certainof the corrugations adjacent the inner edges of the sheets l8-l9 and isprovided with flat marginal edges 30, the flat margins 30 and also thecorrugated portion of the sheet 28 being secured to the sheets 18-19 byrows of rlvets on opposite sides of the overlapped corrugations 2 7.lVith this construction, it will be noticed, the-end structure isprovided with a plurality of tubular beams which extend from the floorof the car to substantially the root so as to provide a central rigidsupport for the roof structure of the ear. By reinforcing the endstructure in this manner it is possible to dis pense with the usual endposts of the car framing and at the same time provide suitablereinforcement to resist the cargo thrusts adjacent the vertical centerline of the car. By forming the corrugations 27 on the sheets 1819 sothat they extend inwardly it is possible to reinforce the verticalcenter portionof the end structure by means of a metal sheet or panelhaving outwardly pressed corrugations without conflicting with theprovisions of the Interstate Commerce Commission relating to theclearances between adjacent cars. This provision requires that twelveinches be provided between the end ladders of adjacent cars for a'distance of thirty inches from the sides of the car. The portion of theend intervening between the end ladders 31, if desired, may extendoutwardly beyond the above prescribed clearance limit.

Referring to Figs. 4 to 6 inclusive, in which I have shown a modifiedconstruction consisting of a plurality of horizontally disposed sheetsformed with parallel corrugations-which extend across the car from sideto side. This modified construction preferably consists of an uppersheet 32, lower sheet 83 and intermediate sheet 3%. The upper edge ofsheet 32 is cut away at an angle corresponding to the slope of the rootand is secured to the end plate 12 of the car by bolts 26 The adjacentedges of the sheets are overlapped as shown at 35-36 and se cured.together and the vertical edges are provided with angular attachingflanges 37 which are secured to the sides of the car by bolts 23% Theabove mentioned sheets are preferably formed with a plurality 01" outwardly pressed corrugations 38 which terminate within the edges of thesheets with tapered terminals 39. The lower edge of the lower sheet isformed with an inturned flange 40 which extends under the flooring ofthe car. The lower portion of the end wall is reinforced byahorizontally disposed metal sheet ll, having a plurality ofhorizontally disposed, inwardly pressed corrugations l2 and having itslower and vertical edges bent rearwardly to provide flanges 43ll-,respectively, corresponding to the flanges s7 ao of the lower sheet 33.The corrugations of the sheets 33- 11 are oppositely disposed withrelation to each other and the sheets are secured together by rows ofrivets on opposite sides of the corrugations. By arranging the sheet 38so that the corrugations 38-ii2 are oppositely disposed with relation toeach other a very rigid structure is provided adjacent the flooring oithe car which will effectively resist such cargo thrusts and alsorigidity the car frame adjacent the floor line.

In Fig. 7 of the drawings 1 have illnstrated a modified construction inwhich the end panel ,is made up preferably'ot four corrugated sheetsconsisting of side sheets ib-A5 and center sheets 4:6"47, which areformed with vertically extending corrugations Q28 and arranged face toface and secured together by rivets 49 at points between thecorrugations. The inner edges of the side sheets a5, :5 are preferablysecured between the vertical edges of the center sheets 46, 47.

In Figs. 8 to ll inclusive I have illustrated another modification inwhich the end panel is made -up of sheets 50, 51 formed with verticallyextending corrugations 52 and overlapped and secured together adjacentthe vertical center of the car as indicated at The upper edges of thesesheets are bent over on diagonal lines to provide flanges 54, 55 whichreinforce the upper portion of the end panel and provide a support forthe ridge pole 56 and purlins 57. The central portion of the end panelis rigidified by means of a vertically extending sheet 'iormed withvertical corrugations which are vertically arranged opposite to saidcorrugations 01 sheets 50. 51'. and the said sheets 50, 51, 58 aresecured together by rivets 59 on opposite sides of the corrugationsoverlapped by the sheet 58. v

in Fig. 12 is shown a further modification consisting of outer sheet 6-)which may be constructed substantially the same as the sheets 50, 51 ofthe modification illustrated in 1 i 8 to 11 inclusive with the exceptionthat the upper edges of the sheets bent eutwardly to provide flanges 61to which the rooi sheets 62 may be secured as indicated at 63. Thisconstruction is also provided with centrally arrai ged verticallyextending sheet 64: having oppositely disposed vertically extendingcorrugations substantially the same as that illustrated in the precedtwospecific embodiments it will be obvious that further modifications instructure might be made without departure from the spirit of myinvention. I therefore do not wish to be limited to the exact structureshown and described except only in so far as specific limitations mayappear in the appended claims.
